Preheat the oven to 400°F. Grease a large baking sheet or dish with non-stick cooking spray.
In a large bowl, beat the egg. Add the remaining ingredients and stir well to combine. Shape the meat mixture into 28 (1-inch) balls. Place on the prepared baking sheet.
Bake for 18 to 20 minutes or until the meatballs reach an internal temperature of 165°F.
Notes
These turkey meatballs are delicious served with pasta and sauce, sprinkled with additional cheese and fresh herbs, or smothered in sauce on a hoagie bun.
To keep the meatballs uniform in size, use a small ice cream scoop or cookie scoop. Having uniformed meatballs will help them cook evenly in the oven.
When rolling the meatballs, do not squeeze them too tightly. You don’t want to pack the meatballs as they’ll become dense.
To make shaping the meatballs easier, wet your hands! When you dampen your hands, the water creates a barrier on your skin, so the meat doesn’t stick, and you can roll them into a ball without causing a mess.
Another way to ensure the meatball mixture is easy to work with, keep the ground turkey in the fridge for as long as possible while you prep the ingredients. It’s much easier to roll the meatballs when the meat is cold.
Careful not to overbake your meatballs. Check on them at the 18-minute mark, as baking turkey meatballs too long will dry them out and make them tough.
If you have trouble mincing your onion small enough to blend into the meatball mixture, you can grate the onion instead.
